45: David Heinemeier Hansson - Software Development and Testing, TDD, and exploratory QA

Summary: <p>David Heinemeier Hansson is the creator of Ruby on Rails, founder &amp; CTO at Basecamp (formerly 37signals). He's a best selling author, public speaker, and even a Le Mans class winning racing driver. </p> <p>All of that, of course, is awesome. But that's not why I asked him on the show. In 2014, during a RailsConf keynote, he started a discussion about damage caused by TDD. This was followed by a few blog posts, and then a series of recorded hangouts with Martin Fowler and Kent Beck. This is what I wanted to talk with David about; this unconventional yet practical and intuitive view of how testing and development work together. </p> <p>It's a great discussion. I think you'll get a lot out of it.</p><p>Special Guest: David Heinemeier Hansson.</p><p>Sponsored By:</p><ul><li> <a rel="nofollow" href="http://testandcode.com/pycharm">PyCharm Professional</a>: <a rel="nofollow" href="http://testandcode.com/pycharm">If you value your time, you owe it to yourself to try PyCharm.
